MACHlNE FOR FORMING NEG-KS OF BOTTLES.

SPECIFICATION forming part of Letters Patent No. 631,329, dated August 22, 1899.

Application filed March 5,1898. Renewed May 4, 1899-. Serial No. '7l5, 89- N m lexclusively used, because the machines for.

this purpose are found incapable of doing the work with precision and econom y. The hand-tool, which requires superior skill for the operator, consists of a central fixed piece or mandrel to form the insideof the neck and two former-pieces mounted on spring-levers which are pressed together upon the neck to be formed by hand. The machines heretofore invented operate substantially on the same principle as the hand-tool. All of these methods are more or less objectionable in that they do not impart a perfect parallel movement to the forming mechanism, and therefore do not uniformly distribute the glass in the neck, but make an irregular-shaped and crooked neck.

My invention aims at overcoming these objections by causing the former to approach upon the neck in parallel lines with even gradual movement, pressing out the glass uniformly and forming a more perfect neck.

The economy and simplicity of my machine consist in forming the necks by a perfect parallel movement of the formers from be ginning to end and having sufficient time for rotating the formers over the shaped neck before hardeningof the glass takes place, thereby giving additional polish to the finished article.

My invention consists of details hereinafter fully described and particularlypointed out in the claims.

Figure 1 is a side elevation of my machine. Fig. 2 is a top view'of a portion of the same. Fig. 3 is a sectional View on lines 3 3, Fig. 1. Fig. 4 is a sectional view on lines t 4, Fig. 1.

. Fig. 5 is an end view of the portion of the machine at the mandrel. View on lines 6 6, Fig. 1. A represents the supporting-bracket; B, the pulley; O, the shaft; D, the bell-crank lever; E, the sliding sleeve; F F, the links; G G, the levers attached to the links F F; H, the mandrel; I I, the formers J J, the parallel bars, to which the formers I I are attached; K, the cleat, which supports the inner ends of J J; L, the abutting block on the mandrel, against which the bottle-neck is pressed; M, the pin in the mandrel, which passes through the formers I I; N, the foot-lever, by which the pressure. at the formers is applied, and O the spring by which the formers are separated.

The shaft C is driven by the pulleys B and carries with it the links F, &c.,' by which the formers I I are operated, the sliding sleeve E being provided with a spline e, which the feather 6 upon the shaft engages. The rollers d d" upon the bell lever-crank D run in the groove d. The links F F are attached one end to the sleeve E and the other end to the levers G G. The levers G G are bifurcated and pivoted on the bolt 0?! at the middle crossing-point to the sleeve 1) upon the shaft 0 and are attached one end to F F and the other end to the parallel bars J J at the pivots g g. The bolts jj extend from one arm to the other of G G and slide in the ways a a in the parallel bars J J. The cleat K is secured to the shaft and rests against the inner ends of J J to support and steady them.

The formers I I are attached to the outer ends of J J by the bolts *6 t'. The mandrel H is attached to the shaft 0 at the joint It, so that it may be removed and replaced when damaged. The block L is attached to the mandrel and forms an abutment against which the top of the neck of the bottle is pressed. The pin M is secured in this block L and passes through the formers I I, which slide in and out on itand are retained in place by it. These formers are given different contours on the inner face, according to the shaped neck it is desired to form on the bottle.

The operation of my invention is as follows: The neck of the bottle to be formed is slipped onto the mandrel H while still soft (the machine being in operation and the formers rotating) and the end of the neck forced up Fig. 6 is a sectional against the block L until the neck is brought l and outwardly in parallel lines, said forming to the proper length. The foot-lever N is then pressed down gradually, bringing the formers I I up about the neck of the bottle and the parts of the machine into the position shown in dotted lines, Fig. 1. The rotation of the formers in this position quickly brings the soft and cherry-red heated glass of the neck into the formers, pressing out the superfluous glass and giving the desired shape to the neck.

It will be seen that by the mechanism which I have described the formers II are made to approach one another in parallel lines instead of swinging on a hinge, as has been heretofore customary in machines of this class. This gives a much more perfect forming effect, and each neck can be brought down more exactly to the same pattern with the least expenditure of power and time.

It will be observed that the formers are supported, through the medium of the bars J J, solely by the levers themselves without employing a cross-head or other guideway for slide-blocks. The movement of the formers is therefore a free one, nnhampered by any sliding action other than that of the bolts in the ways a a.

What I claim, and desire to secure by Letters Patent, is

1. A machine for forming the necks of bottles consisting of the combination of a mandrel portion adapted to be inserted within the neck of a bottle, rotating formers for finishing and forming the bottle-neck, and lever mechanism for operating such formers to and from the bottle in parallel lines, said formers being supported wholly by the lever mechanism, substantially as described.

2. A machine for forming the necks of bottles consisting of the combination of a rotating mandrel adapted to be inserted within the neck of a bottle, rotating forming mechanism laterally movably mounted upon the mandrel so as to be rotated, and levers for moving the formers to and from the bottle in parallel lines, said formers being supported wholly by the lever mechanism, substantially as described.

8. A machine for forming the necks of bottles, the combination of a rotating shaft carrying a rotating mandrel adapted to be inserted in the neck of a bottle, forming mechanism mounted upon the shaft and adapted to be moved in and out to contact the bottleneck, and lever mechanism pivotally connected to the shaft and to the formers to move the formers inwardly and outwardly in parallel lines, said formers being supported wholly by the lever mechanism, substantially as described.
